Hence, the present study was formulated to determine the effect of GnRH administration before and at the time of insemination in mid luteal phase (day 9 to 12 of oestrous cycle) application of CIDR plus PGF2 induced oestrus in crossbred cows.en-USUltrasonographic Evaluation of Ovarian Status, Fertility Assessment and Endocrine Profile on GnRH Administration in Progesterone Induced Oestrus Crossbred CowsThesis
